DETAILED DESCRIPTION OF THE INVENTION
[0022] Referring to the drawings and initially to FIGS. 1-3, a
treadmill in accordance with the preferred embodiment of the
present invention comprises a main body 1, and an angle adjusting
device 2 mounted on the main body 1.
[0023] The main body 1 includes two upright bars 11, two bottom
rods 12, a holding bar 13, two side rods 14, an upper transverse
rod 15, a lower transverse rod 16, a roller 17, a support board 18,
and a belt 19. The support board 18 is mounted between the two side
rods 14, and the belt 19 is mounted on the support board 18. The
upper transverse rod 15 is located between the two side rods
14.
[0024] The angle adjusting device 2 is mounted between the holding
bar 13 and each of the two bottom rods 12 and includes a support
seat 21, an angle adjuster 22, a bolt 23, and a socket 24.
[0025] The support seat 21 is a triangular hollow body mounted on a
respective one of the bottom rods 12. The support seat 21 has a
front side provided with a first cover plate 212 and a rear side
provided with a second cover plate 214. The support seat 21 has two
side walls each formed with an arc-shaped guide slot 213 to
function as an adjusting track of the bolt 23.
[0026] The angle adjuster 22 is mounted between the holding bar 13
and the support seat 21 (or a respective one of the bottom rods 12)
and includes a first connecting section 225 secured to the holding
bar 13 to move therewith, and a second connecting section 226
secured to the support seat 21 and pivotally connected to the first
connecting section 225. Preferably, the second connecting section
226 of the angle adjuster 22 is secured to an inner side of the
second cover plate 214 of the support seat 21. Thus, the holding
bar 13 is pivotally mounted on the bottom rods 12 by the angle
adjuster 22.
[0027] The angle adjuster 22 has an inside provided with a gear
222, an elastic member 223, and a locking pawl 224. The locking
pawl 224 of the angle adjuster 22 is engaged with the gear 222 to
adjust the angle between the first connecting section 225 and the
second connecting section 226.
[0028] The socket 24 is mounted between the two side walls of the
support seat 21, and the bolt 23 is extended through the guide
slots 213 of the support seat 21, the socket 24 and the front end
of each of the two side rods 14 and is screwed into an end of the
upper transverse rod 15, so that the upper transverse rod 15 is
combined with the two side rods 14 by the bolt 23. At this time,
the bolt 23 is located above and rested on the holding bar 13
extended into the support seat 21 as shown in FIG. 2.
[0029] In operation, referring to FIGS. 4-7, when the holding bar
13 is moved upward by the user, the bolt 23 is moved upward by the
holding bar 13, so that the upper transverse rod 15 and the front
ends of the two side rods 14 are moved upward by the bolt 23 so as
to adjust the angle of the support board 18 mounted between the two
side rods 14. At this time, the first connecting section 225 of the
angle adjuster 22 is secured to the holding bar 13 to move
therewith, and the locking pawl 224 of the angle adjuster 22 is
engaged with the gear 222 to fix the lifting angle of the first
connecting section 225 so as to fix and adjust the angle of the
support board 18 mounted between the two side rods 14.
Alternatively, as shown in FIGS. 4 and 5, when the gear 222 of the
angle adjuster 22 is rotated to its end, the elastic member 223
springs the locking pawl 224 away so that the first connecting
section 225 is returned to the original position.
[0030] As shown in FIGS. 7 and 8, when the bolt 23 is unscrewed
from the upper transverse rod 15, the front ends of the two side
rods 14 are released from the upper transverse rod 15, so that the
two side rods 14 and the support board 18 are lifted toward the
upright bars 11 to move upward from the position as shown in FIG. 7
to the position as shown in FIG. 8 to fold the support board 18 so
as to reduce the volume of the treadmill when not in use, thereby
facilitating storage and transportation of the treadmill. At this
time, the support board 18 is perpendicular to the bottom rods
12.
[0031] Referring to FIGS. 9-12, the angle adjuster 22 is mounted
between the lower transverse rod 16 and a respective one of the two
side rods 14, wherein the first connecting section 225 is secured
to the lower transverse rod 16 to move therewith, and the second
connecting section 226 is secured to a respective one of the two
side rods 14. Thus, when the lower transverse rod 16 is moved
inward, the rear ends of the two side rods 14 are moved upward so
as to adjust the angle of the support board 18 mounted between the
two side rods 14.
[0032] Accordingly, when the holding bar 13 is moved upward by the
user, the bolt 23 is moved upward by the holding bar 13, so that
the upper transverse rod 15 and the front ends of the two side rods
14 are moved upward by the bolt 23 so as to adjust the angle of the
support board 18 mounted between the two side rods 14. In addition,
the user only needs to hold and lift the holding bar 13 so as to
adjust the angle of the support board, thereby facilitating the
user adjusting the angle of the support board.
[0033] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
